At Ultrices Leak Detection, we perform fast bathroom leak detection using ultrasound. We listen to water pipes and drains with an ultrasonic sensor and trace a hidden leak without breaking anything. This way, you limit damage.
We check the shower, bath, toilet, mixer tap, siphon, sealant edge, tiled floor, wall, and ceiling. If you hear ticking or see moisture, we locate the leak using leak detection, pressure testing, and moisture measurement, and provide a report for your insurance.

What is ultrasonic bathroom leak detection
Ultrasonic bathroom leak detection involves the targeted detection of water loss in pipes, drains, and connections using high-frequency sound waves outside the audible range. Ultrasonic sound waves travel through materials and air and are picked up by piezoelectric sensors that convert small pressure fluctuations into electrical signals. Using acoustics and signal analysis, such as Fast Fourier transformation, we make the leak noise visible in a frequency spectrum. At Ultrices Leak Detection, we combine this science with practical knowledge of bathroom construction, from PEX and copper water pipes to siphons, shower drains, and sealant joints. This allows you to locate the leak quickly and without unnecessary demolition work, with an accuracy that is insurable and remains reproducible in our expert report.
How ultrasonic leak detection works in the bathroom
When water under pressure escapes from a hairline crack, coupling, or pore, a characteristic broadband signal is generated. This signal lies in the ultrasonic range and becomes stronger around bottlenecks, bends, and connections. Using contact probes and air ultrasonic microphones, we filter out ambient noise and focus on the relevant dB and Hz range. We use professional detection equipment such as acoustic correlators, ultrasonic microphones, and acoustic imaging cameras, including the Fluke ii900, FLIR Si124, and Trotec measurement technology. By correlating two measurement points, we determine the exact leak position on pipes behind tiling or in the screed. In wet zones, such as the shower floor, we combine ultrasound with additional measurements to reliably distinguish resonance and flow noise from the drainage system.
Our no-break method
Our ultrasonic bathroom leak detection process is designed to work quickly, safely, and non-destructively. You keep your bathroom intact while gaining rock-solid certainty. Here is how we do it.
- Intake and contextWe discuss complaints, year of construction, materials, and previous repairs, and check pressure loss and water meter reading.
- Calibration and baseline measurementWe measure the background noise and select the appropriate filter and bandwidth so that interference is suppressed.
- Ultrasonic scanWe listen specifically for hot and cold water and for drainage routes, using contact and air probes along walls, floor, and ceiling.
- Correlation and pinpoint: we place two sensors and calculate the time differences to pinpoint the exact leak position.
- VerificationWe validate with additional methods such as dye testing, endoscopy, thermography, or tracer gas if necessary.
- Report and adviceYou will receive an expert report within three days with photos, spectrums, and repair advice that meets insurer requirements.

Types of ultrasonic detection and combination techniques
- Airborne ultrasound: Detection with ultrasonic microphones picks up airborne leakage noise, ideal for inaccessible places or cove spaces, with frequent filtering to separate ventilation noise.
- Structure-bound ultrasoundContact probes register vibrations in walls and floors, effective for pipes in screed or behind tiling and less sensitive to ambient noise.
- Acoustic correlation: Two sensors calculate the distance to the leak between measurement points via cross-correlation, very precisely for longer runs or multilayer pipes.
- Acoustic imagingAn acoustic camera projects the leak sound as a thermal image-like overlay, accelerating localization around bottlenecks such as mixing valves and manifolds.
- Hybrid approach: combination with thermography, pressure test in accordance with NEN 1006, and tracer gas with hydrogen nitrogen for maximum certainty in the event of silent or intermittent leaks.
Common causes and symptoms in the bathroom
- Errors in sealing seams and jointsWater seeps behind tiling due to faulty sealing around the shower and bath, causing mold edges and peeling plaster.
- Hairline crack in pipe or coupling: press fittings or solder joints leak under pressure and produce a ticking sound, with damp patches on the ceiling below.
- Drain and siphon problemsLeaking siphons and slipping seals cause unpleasant odors and wet spots after showering or bathing.
- Penetrating moisture through floor structure: Failing base detail or membrane causes rising damp and discoloration in adjacent rooms or skirting boards.
- High water bill and pressure lossUnexplained consumption and dropping boiler pressure are strong signals that we confirm acoustically.

Frequently asked questions
What is ultrasonic bathroom leak detection and how exactly does it work?
With ultrasonic leak detection, we apply slight pressure to pipes or drains and listen for the characteristic whistling leak sound using a directional microphone in the high frequency range around forty kilohertz. Our sensors filter out ambient noise and translate the signal into audible tones and clear measurements. This allows us to locate the source to within centimeters of water pipes, drains, shower drains, joints, or siphons.
At Ultrices Leak Detection, we work entirely non-destructively, meaning no hacking or breaking. We combine directional microphones with contact probes for precise pinpointing behind tiling and concealed taps. With VCA VOL and NEN 3140 certification, professional measuring equipment, and over fifteen years of experience, we deliver fast and safe results with a proven ninety-nine percent success rate and a no cure, no pay policy.
How accurate is ultrasonic leak detection for hidden pipes under tiles or built-in shower faucets?
Ultrasound is particularly precise because turbulence at the leak creates a unique acoustic profile. We scan surfaces with a parabolic directional microphone and listen directly to valves, couplings, and pipes with a piezo contact probe. Through frequency analysis and noise filtering, we determine the hotspot to within centimeters, even through tiling.
For built-in shower taps and under tiled floors, we follow the pipe layout and check couplings, sleeves, and bushings. If the background noise is high or the signal is weak, we amplify the pressure with a targeted pressure test and repeat the measurement. This provides certainty without breaking open the pipes, with clear markings on the floor or wall for targeted repairs.
How much does ultrasonic bathroom leak detection cost and how quickly do you receive an insurance report?
The price depends on the complexity, location, and accessibility of the bathroom, and whether it involves supply lines or drainage. After a brief intake, you will receive a free fixed-price quote within twenty-four hours. An inspection usually takes sixty to one hundred and twenty minutes, and in urgent cases, we are often on-site within one hour. No cure, no pay makes your inspection one hundred percent risk-free.
You will receive a comprehensive expert report within three days, including photos, measurement data, and a clear cause analysis. We work with insurers nationwide and offer a guarantee of coverage; please note that final coverage depends on policy conditions.

When do you choose ultrasound, and when a camera or thermography in the bathroom?
Choose ultrasound for pressure pipes to eliminate noises from a shower drain or suspicious grout that shows no visible cracks. It works perfectly for micro-leaks where water hisses through a tiny opening. For drains, we can, if desired, deploy an ultrasonic transmitter in the siphon to follow the path of the sound.
Camera inspection is ideal when you want to visually inspect a drainpipe or shaft and identify obstructions or cracks. Thermography is particularly effective for hot water pipes and underfloor heating because temperature differences reveal patterns. If you are unsure which approach suits your specific issue, please check our explanation of bathroom leak detection with camera and make the best choice for each situation.
